Eh... it varies across... well, so many things: culture; family values; the couple's impulses etc. etc.
For example, at work, there are three women, all of whom married in their twenties. Oddly, the one who married youngest (22, and bizarrely had a friendship-marriage pact for age 24!) is the one who isn't pregnant... the other two married at 23/24. Granted, none of them are western European, so I'm thinking it's a cultural thing that encourages them to marry young. On the flipside, still at work, my boss has been with the same girl since before going to uni (he's 26) and they've only just moved in together. His boss got married in his thirties... every couple is thoroughly happy/content etc.
And then, there's my sister... 33 and getting married in 26 days' time... -_-
So, for it to 'work', I don't really think age has anything to do with it. Some couples can marry within a year of the first date, though I'll admit, it's getting rarer these days, and still be married when they've got great-grandkids. Others just aren't the marrying type, irrespective of age... *shrug*
